What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula
To convert steps into generations, Nilsson and Pelger applied the standard quantitative-genetics equation for the response to selection on a continuous trait, deliberately choosing pessimistic values for every free parameter: a heritability of 0.50, a selection intensity of 0.01, and a coefficient of phenotypic variation of 0.01, values the authors describe as common or deliberately conservative rather than favourable to a fast result [ 4 ] . Those choices give a fractional improvement of only 0.005 percent of the trait mean per generation. Compounding that per-generation rate to reach the full 1,829 steps of one-percent change — equivalent to a single structure lengthening by a factor of…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
